“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”

Keychron K2 HE vs K3 V3: your questions
The K2 HE uses Gateron double-rail magnetic switches, which are contactless and allow for adjustable actuation points. The K3 V3 uses low-profile mechanical switches, specifically Keychron Milk POM switches, which have a traditional mechanical design but in a much slimmer form factor.
The Keychron K2 HE is better for wireless gaming. It includes a 2.4 GHz wireless connection with a 1000 Hz polling rate, alongside Bluetooth. The K3 V3 lacks a 2.4 GHz dongle and uses Bluetooth with a 90 Hz polling rate, which may introduce more latency.
No, the Keychron K3 V3 is a low-profile keyboard. It requires specific low-profile keycaps, such as the LSA profile keycaps it comes with, which are designed for its reduced switch height.
Yes, according to its product description, the Keychron K2 HE features an Analog Mode. This allows for variable, gamepad-like input based on how far a key is pressed, rather than simple on/off signals.
The Keychron K2 HE has a larger 4000mAh battery compared to the K3 V3's 1550mAh battery. While actual runtime depends on usage, the K2 HE's capacity suggests potentially longer wireless operation between charges.
Yes, both the Keychron K2 HE and K3 V3 are listed as hot-swappable. However, each has specific switch compatibility: the K2 HE works only with Gateron double-rail magnetic switches, while the K3 V3 works with Keychron Milk POM and other compatible low-profile mechanical switches.
Yes, both keyboards support key remapping and macro programming. They use open-source QMK firmware and are compatible with the VIA configurator and Keychron's own Launcher web app for customization.
The Keychron K3 V3 is significantly more portable. It weighs 540g and is 19mm tall, whereas the K2 HE weighs 1743g and is 36mm tall. The K3's slim, low-profile design is much easier to pack and use on the go.
Yes, both the Keychron K2 HE and K3 V3 are listed as compatible with macOS and Windows. Each includes keycaps for both operating systems and has a system toggle switch.
The Keychron K2 HE uses screw-in PCB stabilizers. The K3 V3 listing mentions redesigned stabilizers but does not specify the mount style. Screw-in stabilizers, like those on the K2 HE, are often preferred by enthusiasts for modding.
The extra features list for the Keychron K2 HE includes 'Knob Support,' suggesting a variant or modding potential for a rotary encoder. The K3 V3 listing does not mention any knob support.
